Library Description
Library contains generic functions for controlling the waveform and frequency
output of the click board.
Key functions:
void waveform_sineOutput(uint32_t f)
- Function for setting the sine wave output.void waveform_triangleOutput(uint32_t f)
- Function for setting the triangle wave output.void waveform_squareOutput(uint32_t f)
- Function for setting the square wave output.Examples description
The application is composed of the three sections :
void applicationTask()
{
char rxDat;
uint32_t freqTmp;
if(UART_Rdy_Ptr())
{
rxDat = UART_Rd_Ptr();
mikrobus_logWrite(&rxDat,_LOG_BYTE);
}
if(rxDat>0)
{
switch(rxDat)
{
case waveform_cmd[0]: {
waveform_digipotInc();
rxDat = 0;
break;
}
case waveform_cmd[1]: {
waveform_digipotDec();
rxDat = 0;
break;
}
case waveform_cmd[2]: {
freq += 1;
freqTmp = freq << 14;
waveform_sineOutput(freqTmp);
rxDat = 0;
break;
}
case waveform_cmd[3]: {
freq -= 1;
freqTmp = freq << 14;
waveform_sineOutput(freqTmp);
rxDat = 0;
break;
}
case waveform_cmd[4]: {
freq += 1;
freqTmp = freq << 14;
waveform_triangleOutput(freqTmp);
rxDat = 0;
break;
}
case waveform_cmd[5]: {
freq -= 1;
freqTmp = freq << 14;
waveform_triangleOutput(freqTmp);
rxDat = 0;
break;
}
case waveform_cmd[6]: {
freq += 1;
freqTmp = freq << 14;
waveform_squareOutput(freqTmp);
rxDat = 0;
break;
}
case waveform_cmd[7]: {
freq -= 1;
freqTmp = freq << 14;
waveform_squareOutput(freqTmp);
rxDat = 0;
break;
}
default : {
break;
}
}
}
rxDat = 0;
}
Additional Functions :
uint32_t waveform_aproxFreqcalculation(float freqency)
- This function is used to calculate the aproximate value that will be written to the frequency set register.Other mikroE Libraries used in the example:
SPI
UART
Conversions
C_Sring
Additional notes and informations
Depending on the development board you are using, you may need USB UART click, USB UART 2 click or RS232 click to connect to your PC, for development systems with no UART to USB interface available on the board. The terminal available in all MikroElektronika compilers, or any other terminal application of your choice, can be used to read the message.
